Debian Security Advisory DSA 315-1                     security@debian.org

--------------------------------------------------------------------------

Package        : gnocatan
Vulnerability  : buffer overflows, denial of service
Problem-Type   : remote

Bas Wijnen discovered that the gnocatan server is vulnerable to
several buffer overflows which could be exploited to execute arbitrary
code on the server system

For the stable distribution (woody), this problem has been fixed in
version 0.6.1-5woody2.

The old stable distribution (potato) does not contain a gnocatan package.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your gnocatan package.

Upgrade Instructions
--------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
